Why cant you watch TV if you have a concussion?

Watching TV after a concussion can exacerbate symptoms such as headaches, dizziness, and visual disturbances due to the screen's brightness and rapid movements. The cognitive load required to process visual and auditory information can also hinder recovery by overstimulating the brain. It's generally recommended to rest and limit screen time to allow for proper healing. Always consult with a healthcare professional for personalized advice.
